I made a reservation over the phone and cause of a technical issue where the property could not pull up my reservation, SPG canceled and rebooked a few times till they resolved the issue.
However now that I log into my account I see that I have 2 reservations and was only changed for one room. I'm traveling with kids and I wouldn't mind the extra room.
If I checkin to both rooms is there a chance they will figure it out the mistake and charge me for the second room?.
